Ghost circuit shorts under smt resisters only when they are located on solder side of pcb (glued down)

We are having a process related problem with pullup resistors on a controller card which has a I960 micro-processor. The controller monitors signal inputs and it's own resources then blinks a LED to indicate its working. The problem is that after a p

what type of belt is it and what material is it? round belt, flat belt, etc... if its from a PCB transport conveyor or other PCB handling system, I recommend you contact the OEM. I have spliced belts before- rubber round belt off old Fuji loader and

Round Solder Lands

Electronics Forum | Fri Mar 02 06:25:04 EST 2001 | PeteC

Thanks for your feedback. All the 0603 chips have the round solder lands but the 0805 chips and larger are rectangular. After speaking with the designer on it he said they chose round lands for the 0603 chips to get higher density of the circuit trac
